Calculation of third order elastic constants of crystals
of alloy based on TiNi with shape memory
S. A. Muslov, A. I. Lotkov
The numerical relationships between third-order elastic constants cijk of TiNi alloy crystals with shape memory effect were obtained for the first time. TiNi-based alloys are well known and are widely used in engineering and medicine due to their unique effects of superelasticity and thermomechanical shape memory. Until recently, data on the elastic properties of this alloy remained incomplete mainly due to technical difficulties in obtaining single crystals of alloys. In addition, in the literature there are still insufficiently consecrated questions and working design formulas that make it possible to determine elastic constants of the third order of materials on the basis of ultrasonic measurements, formulas from theoretical sources are cumbersome and contain many physical parameters, some of which are sometimes unknown. In this report, equations are obtained relating the numerical values of third-order elastic constants of TiNi – 2 % Fe alloy crystals to shape memory on the basis of simplified formulas, proper and published data. Approximate numerical values of elastic constants are calculated taking into account the Cauchy conditions.
Key words: third order elastic constants, shape memory.

N. N. Kolobylina, E. V. Todorova
The microstructure of Al85Ni5Fe7La3 amorphous alloy after high-speed quenching, isothermal annealing and flash lamp annealing was studied by means of transmission electron microscopy, including high-resolution transmission electron microscopy, electron and X-ray diffraction, energy dispersive X-ray microanalysis, and differential scanning calorimetry. A comparative analysis of the structures with respect to phase composition and phase morphology is carried out. It was shown that after the quenching, an X-ray amorphous structure is formed in the alloy. There were established critical parameters of heat treatment of the amorphous alloy which lead to single-phase or multiphase crystallization, a volumetric or gradient structure. Based on a complex analysis of these types of determinations, the phase composition of the nanocomposite formed during crystallization. The identity of the emerging structures with respect to the phase composition and phase morphology is determined for certain parameters of isothermal and flash lamp annealing, with close values of microhardness, which significantly exceed the hardness of the alloy in the amorphous state.
Keywords: Amorphous alloy, structure, flash lamp annealing, nanocrystallization, composite, heat treatment.

Structure and properties of gas-filled bio-composites
on the base of polyethylene
E. A. Grigoreva, N. N. Kolesnikova, A. A. Popov, A. A. Olkhov
Gas-filled composite materials were derived through foaming polyethylene of law density with chemical foaming agent and injecting natural components. A chemical disperse blowing agent hydrocerol was used to make the polyethylene structure porous. Disperse biodegradable fillers, wood flour and corn starch, were used as natural components. Investigation of structure, physical and physical-mechanical properties of the materials was held. It is shown, that the structure of polyethylene became heterogeneous: pores and alien inclusions appeared. The density and operational properties decreased. It is noted, that such peculiar properties of the material as low density, voids and particles of hygroscopic filler, increase the possibility of biodegradation. The ability of materials to degrade in the environment was investigated by the method of measurement of weight loss in soil and water absorption. Results of this measurement demonstrate weight loss in soil of composite samples, which is may be explained by the destructive effect of microorganisms, partial washing of the filler and fragmentation of the sample. The obtained samples of gas-filled composite materials, with reduced but maintained at a sufficient level of performance properties, have shown the promising outlook of their application as packaging materials and sealing elements of packaging and tare for non-food consumer goods.
Keywords: polyethylene, hydrocerol, wood flour, starch, gas-filled composite materials, pores, biodegradation.

Deformation and fracture of amorphous
and crystalline wires
of medical usage at torsion

The mechanisms of deformation and fracture of the “thick” amorphous wires of the Co69Fe4Cr4Si12B11 alloy and crystalline medical wires from steel AISI 304 and nitinol were studied at one-sided and two-sided twisting before fracture. It is established that the high ability to twist the crystal wires is due to the flow of intense plastic deformation along the length of the wire. Fracture of crystalline type wires can lead to tissue damage in the fracture of the medical instrument. Twisting of amorphous wires occurs in the elastic region. Plastic deformation is realized locally at the last step of twisting and is about 20%. The characteristic zones of fracture of the amorphous wire after twisting were established. The possibility of an almost double increase in the ability to twist an amorphous wire in a two-sided twist is obtained by forming a tangential net of shear bands on the wire surface. The ability of amorphous wire to exhibit superelastic properties and high ductility when twisting opens up the possibilities for developing new types of medical instruments. Amorphous wires can be of interest for the manufacture of medical instruments and products due to the high level of mechanical, magnetic and corrosive properties superior to crystalline analogs.
Keywords: amorphous wire, twisting, medical instrument.

Curing of ED-20 epoxide resin with diesterdisulfoanhydride
of 2-hydroxypropyl of saccharin-6-carboxylic acid
E. T. Aslanova, T. A. Aslanov, B. A. Mamedov, A. A. Mamedova
By interaction of monoanhydride of sulfoimide of saccharin-6-carboxylyc acid with 1,3-diacetine there has been obtained diesterdisulfoanhydride of 2-hydroxypropyl of saccharin-6-carboxylic acid. The composition and structure of the synthesized compound has been confirmed by data of elemental analysis and IR-spectroscopy. The obtained product was used as a curing agent — plasticizer for industrial epoxide resin ED-20. It has been istablished that the diesterdisulfoanhydride of 2-hydroxypropyl of saccharin-6-carboxylic acid is the effective curing agent — plasticizer of epoxide resin ED-20. The curing prosses of composition was studied by a method of differential thermal analysis on derivatograph of system “Paulik-Paulik-Erdey”. It has been revealed according to the received data that the synthesized diesterdisulfoanhydride is combined well with epoxide resin ED-20 but cures it at hard temperature regime. It has been shown that as a result of using metylendyc anhydride as cocuring agent-accelerator the curing temperature range of composition is shifted to more low temperature zone. On results of elemental analysis and
IR-spectroscopy the composition and structure of the initial epoxide resin and cured products has been also proved.
Key words: diesterdisulfoanhydride, plastificizer, curing, composition.

The strategy for synthesis of the materials with a switchable wettability based on photosensitive terpolymers containing poly(titanium oxide)
O. A. Ryabkova, E. V. Salomatina, A. V. Knyazev, L. A. Smirnova
The organic-inorganic terpolymers based on poly(titanium oxide) ((≡TiO)n), hydroxyethyl methacrylate (HEMA) and different organic vinyl monomers (styrene, vinyl butyl ether, butyl methacrylate, isobornyl acrylacrylate, 2-ethylhexyl acrylate, acrylonitrile, methyl methacrylate) have been synthesized by a polycondensation-polymerization method. The terpolymers are optically transparent in the visible spectral range (T ~ 90 %) independent on the composition. As it was observed the materials had an amorphous structure, and the poly(titanium oxide) chains were self-organized into nanoclusters by the type of anatase inside of terpolymers. The darkening of terpolymers took place under UV-irradiation a result of the reversible photochromic one-electron transition The rates of the direct and reverse one-electron transition can be controlled by the change of the monomer units nature and its molar ratio in terpolymers. These changes also lead to a modification of the tensile strength of the materials. The greatest depth of change in light transmittance over 180 minutes of UV-irradiation was observed in terpolymers with styrene, butyl methacrylate and acrylonitrile units — by 55 %, 70 % and 60 %, respectively, at a molar ratio of the components [(≡TiO)n]:[HEМА]:[М] = 1:5:1. The higher reaction rates of the transition (discoloring) were observed for these materials, as well as for terpolymers with vinyl butyl ether units. The materials were demonstrated the effect of photoinduced superhydrophilicity under UV-irradiation, the contact angle of the surface is reduced by ~ 60 °.

Surface modification of corundum ceramics
by argon ion beam
S. A. Gyngazov, V. Kostenko, V. V. Ovchinnikov,
N. V. Gushchina, F. F. Makhinko
The mechanical properties of near-surface layers of aluminum oxide ceramics treated with a continuous ion beam of argon are investigated. The phase and structural changes of the modified near-surface layers were analyzed by X-ray diffraction analysis and scanning electron microscopy, respectively. Samples for research were made from corundum plates used in microelectronics. Ion processing was carried out on an ILM-1 ion implant equipped with an ion source «Pulsar-1M» based on a low-pressure glow discharge with a cold hollow cathode. For irradiation, argon ions with an energy of 30 keV and an ion current density j = 300 μA/cm2 were used. Two irradiation modes with fluences of 1016 and 1017 cm–2 were realized. It has been established that ion treatment promotes the manifestation of the initial grain structure of the sample and increases the mechanical characteristics (modulus of elasticity and nanohardness) of the near-surface layers of the samples. According to X-ray diffraction studies, after the action of the ion beam, there is a decrease in the size of the coherent scattering region relative to the initial state. Irradiation leads to an increase in the value of the microstrains of the crystal lattice. Possible mechanisms for modifying the ceramic surface are discussed.
Key words: alumina ceramics (corundum), ion beams, mechanical characteristics, X-ray phase analysis.

Plasma-chemical modification of facing composite
material on the basis of hollow glass microspheres
with protective and decorative coating
D. O. Bondarenko, V. V. Strokova, T. I. Timoshenko,
I. V. Rozdol’skaya
The paper considers plasma-chemical modification of the facing composite material on the basis of hollow glass microspheres with protective-decorative coatings. It is shown that the technology of obtaining protective-decorative coating by the method of plasma reflow is highly efficient, energy-saving, which will allow to compete with traditional technologies and significantly reduce the cost of finishing work. The compositions of protective and decorative coatings based on high-alumina refractory and liquid glass have been developed. It was revealed that the use of high-alumina refractory battles in the intermediate layer allows to reduce the number of microcracks and eliminate the consequence of high-temperature impact on the matrix of fine-grained concrete. The positive effect of hollow glass microspheres on the minimization of thermal shock was established. The results of the investigation of the effect of plasma-chemical modification on the phase composition and structural features of the facing composite material on the basis of hollow glass microspheres with a protective-decorative coating are presented. The regularity of layer-by-layer variation of the phase composition, macro- and microstructure of the protective and decorative coating of the facing composite material is established. It is shown that the upper layer is represented by Na – Ca – Al – Si glass, the middle glass-crystalline layer is represented by the glass phase and α, β-modifications of aluminum oxide, the lower dehydration layer by dehydration products of hydrosilicates and α, β-modifications of alumina. High-temperature action of the plasma jet intensifies thermal diffusion, which in turn leads to a redistribution of oxides along the thickness of the protective and decorative coating.
Keywords: blister composite, plasma-chemical modification, protective decorative coating, hollow glass microspheres, alumina modifications.
